Title:
焦点検出装置およびそれを有する撮像装置
Document Type and Number:
Japanese Patent JP5451111
Kind Code:
B2
Abstract:
A focus detection device having imaging pixels and focus-detecting pixels using a phase-difference focus detection method implements high-precision focus detection. In the focus detection device, a plurality of pixels each having a photoelectric conversion unit for converting an incident light flux into signal charges, and a microlens having a focus position near the photoelectric conversion unit are arranged. The plurality of pixels include a plurality of imaging pixels for generating a shot image, and a plurality of focus-detecting pixels for generating an image signal for focus detection by the phase-difference focus detection method. An opening for giving a pupil division function to the focus-detecting pixel is formed using electrodes arranged to read out signal charges from the photoelectric conversion unit.
